# Standard Deviation

## Overview

The standard deviation is a metric which is used to measure the amount of variation in a set of data values.

The standard deviation has the same units as the data.

## Software

You can calculated the standard deviation of an array in Numpy with np.std():

np.std(my_array)

By default, the array is flattened. However, you can specify an axis on which to calculate the standard deviation.
